Research question: Agri-environment schemes play an increasingly important role in European CAP (Common Agricultural Policy) to support biodiversity and environment in agricultural landscapes. They have been implemented since 1992 and now cost a yearly 1.7 billion Euro. Still, there is no conclusive evidence that these schemes actually do contribute to the conservation of particularly biodiversity. The primary objective of this project is to evaluate the (cost-) effectiveness of European agri-environment schemes in protecting biodiversity and to determine the primary processes that determine their effectiveness. This project furthermore aims to determine how CAP may be introduced in candidate EU-members without unacceptable loss of biodiversity. It will provide simple guidelines how researchers, governmental authorities may efficiently evaluate agri-environmental measures. Aim: Agri-environment schemes have been used to protect biodiversity and environment in agricultural areas since 1992. Their effectiveness has never been reliably evaluated. This project aims to evaluate the (cost-)effectiveness of agri-environment schemes with respect to biodiversity conservation in five European countries. It will determine the proper scales that have to be addressed for conservation efforts for a range of species groups. It will determine the most important environmental factors that influence the effectiveness of the schemes. Based on this, recommendations will be made how the effectiveness of schemes may be improved and simple guidelines will be produced how ecological effects of agri-environment schemes can be evaluated efficiently by governmental authorities or other institutions. The ecological effects of the introduction of CAP in a candidate EU-member will be investigated to reduce negative side effects of anticipated land-use changes Scientific methods: We will examine the effectiveness of agri-environment schemes by surveying pairs of fields: a field with an agri-environment scheme and a nearby field that is conventionally managed. In five countries, in each country in three areas, and in each area on seven pairs of fields the species richness of birds, plants and three insect groups (pollinators, herbivores, predators) will be determined. Effects of schemes on pollination efficiency and pest control will be examined using indicator communities. Correlative studies will examine the effects of landscape structure, land-use intensity and species pool on the effectiveness of agri-environmental measures. The spatial scale that is relevant to nature conservation efforts will be investigated via the spatial distribution of species groups. The results will be used to formulate recommendations how to improve the effectiveness of agri-environment schemes and to construct a set of simple guidelines how schemes can be evaluated efficiently yet reliably.

The present-day configuration of Indonesia and SE Asia is the results of a long history of tectonic movements, volcanisms and global eustatic sea-level changes. Not indifferent to these dynamics, fauna and flora have been evolving and dispersing following a complicate pattern of continent-sea changes to form what are today defined as Sundaland and Wallacea biogeographical regions. The modern intraannual climate of Indonesia is generally described as tropical, seasonally wet with seasonal reversals of prevailing low-level winds (Asian-Australian monsoon). However at the interannual scale a range of influences operating over varying time scales affect the local climate in respect of temporal and spatial distribution of rainfall. Vegetation generally reflects climate and to simplify it is possible to distinguish three main ecological elements in the flora of Malaysia: everwet tropical, seasonally dry tropical (monsoon) and montane. Within those major ecological groups, a wide range of specific local conditions caused a complex biogeography which has and still attract the attention of botanists and biogeographers worldwide. Being one of the richest regions in the Worlds in terms of species endemism and biodiversity, Indonesia has recently gone through intensive transformation of previously rural/natural lands for intensive agriculture (oil palm, rubber, cocoa plantations and rice fields). Climate change represents an additional stress. Projected climate changes in the region include strengthening of monsoon circulation and increase in the frequency and magnitude of extreme rainfall and drought events. The ecological consequences of these scenarios are hard to predict. Within the context of sustainable management of conservation areas and agro-landscapes, Holocene palaeoecological and palynological studies provide a valuable contribution by showing how the natural vegetation present at the location has changed as a consequence of climate variability in the long-term (e.g. the Mid-Holocene moisture maximum, the modern ENSO onset, Little Ice Age etc.). The final aim of my PhD research is to compare the Holocene history of Jambi province and Central Sulawesi. In particular: - Reconstructing past vegetation, plant diversity and climate dynamics in the two study areas Jambi (Sumatra) and Lore Lindu National Park (Sulawesi) - Comparing the ecological responses of lowland monsoon swampy rainforest (Sumatra) and everwet montane rainforests (Sulawesi) to environmental variability (vulnerability/resilience) - Investigating the history of human impact on the landscape (shifting cultivation, slash and burn, crop cultivation, rubber and palm oil plantation) - Assessing the impact and role of droughts (El Niño) and fires - Adding a historical perspective to the evaluation of current and future changes.
The project's objective is to support JRC IPTS in revising the existing Ecolabel and GPP criteria of personal computers and notebook computers. The priority in this revision process is to first analyse which of the existing criteria and the supporting evidence are still valid and to identify the additional research that should be carried out. Potential additional criteria can be developed, if identified as necessary in the course of the study. The study starts with a definition of the scope; the necessarity for new or revised Ecolabel and GPP criteria is based on a market analysis and a technical analysis with research on the most significant environmental impacts during the whole life cycle of the products. This also includes the application of a consistent methodological approach regarding the hazardous substances criteria. Based on these findings, the improvement potential will be derived resulting in a proposal for a revised Ecolabel and GPP criteria set for desktop and notebook computers which will be discussed in a European stakeholder process.
Der schnelle Fortschritt der elektronischen Geräte erhöht die Nachfrage nach verbesserten Li-Ionen Batterien. Kommerziell erhältliche Li-Zellen nutzen meist Lithiumkobaltoxid für die positive Elektrode. Doch gerade dieses Material ist ein Hindernis für eine weitere Optimierung, insbesondere für eine Kostensenkung. Vor allem für größere Anwendungen wie Hybrid- oder Elektrofahrzeuge müssen alternative Materialen erforscht werden, die billiger, sicherer und umweltverträglicher sind. Daher wird im ISEA derzeit ein neues Forschungsprojekt ins Leben gerufen und die dafür benötigte Infrastruktur geschaffen. Die Forschung wird sich auf die Untersuchung geeigneter Übergangsmetalloxide und Polyanionen konzentrieren, die besonders gut zur Einlagerung von Li-Ionen geeignet sind. Es werden neue Herstellungsverfahren unter Verwendung wässriger Precurser-Substanzen untersucht, die Verbindungen mit überlegenen Eigenschaften erzeugen und außerdem leicht an eine Massenproduktion angepasst werden können. Ziel der Arbeiten ist, preisgünstiges Elektrodenmaterial zu entwickeln, das eine spezifische Energie von über 200 Wh/kg und eine Leistungsdichte von 400 W/kg aufweist. Außerdem werden Arbeiten im Bereich der physikalisch-chemischen Charakterisierung der neuen Materialien stattfinden sowie elektrochemische Analysen der gesamten Zellen- und Batteriesysteme durchgeführt. Das elektrodynamische Verhalten der neuen Zellen wird u. a. mit Hilfe der elektrochemischen Impedanzspektroskopie analysiert, um präzise und zuverlässige Algorithmen für ein späteres Batteriemonitoring im realen Betrieb zu finden.
Ziel der Forschungsarbeit ist die Klassifizierung von Boden-Biozönosen in ausgewählten Feldrainen. In drei Naturräumen (Lössböden der Jülicher Börde, Muschelkalkböden in Mainfranken und pleistozäne Sande bei Leipzig) werden typische Lebensgemeinschaften von Collembola und Gamasina (Taxozönosen) beschrieben. Der wesentliche Unterschied zu anderen Klassifikations-Ansätzen liegt in der induktiven Vorgehensweise: Biozönosen werden allein aufgrund der Artenzusammensetzung an den Standorten typisiert. Vegetationskundliche Kriterien dienen als entscheidendes Hilfsmittel zur Vorauswahl von Flächen mit ähnlichen Standortbedingungen. Hierbei wird gleichzeitig die aufgenommene Vegetation als ein weiteres Taxon der zu beschreibenden Biozönose angesehen. Die typische Artenzusammensetzung ist das integrierte Ergebnis aller denkbaren ökologischen Vorgänge. Ein Ziel der Arbeit ist somit die prospektive Formulierung von Erwartungswerten für Collembolen und Raubmilben auf der Basis vegetationskundlicher Daten. Es sollte daher möglich sein, dieses Mehrarten-System mit hoher Sensibilität zur Bioindikation von Standortveränderungen einzusetzen. Die Kenntnis der Artenstruktur wiederkehrender Lebensgemeinschaften kann der funktionellen Ökosystemforschung hilfreiche Hinweise bieten.
During the first project period we developed a general approach to quantify soil pore structure based on X-ray micro-tomography Vogel et al. (2010) which is applicable at various scales to cover soil pores larger that 0.05 mm in a representative way. Based on this method we generated equivalent network models to numerically simulate flow and transport of dissolved chemicals. The existing network model was extended to handle reactive transport and infiltration processes which are especially critical for matter flux in soil. The results were compared to experimental findings. The original research question 'what does a particle see on its way through soil' could be answered quantitatively for various boundary conditions including steady state flux and infiltration. However, we identified various critical aspects of the proposed modeling concept which will be in the focus of the second period. This includes 1) the spatial arrangement of interfaces having different quality which is crucial for chemical interactions and pore scale water dynamics, 2) the realistic multiphase dynamics at the pore scale which need to reflect the dynamic pressure and movement of trapped non-wetting phase and 3) the parametrization of structural complexity which need to be developed beyond the measurement of continuous Minkowski functions to allow the development of quantitative relations between structure and function. These aspects will be explored in a joint experiments in cooperation with partners within the SPP.
We will compare the role of an RNA-binding protein in floral transition in Arabidopsis thaliana and Hordeum vulgare. The RNA-binding protein AtGRP7 promotes floral transition mainly by downregulating the floral repressor FLC via the autonomous pathway. Based on our observation that AtGRP7 affects the steady-state abundance of a suite of microRNA precursors, we will globally compare the small RNA component of the transcriptome during FTi regulation in wild type plants and AtGRP7 overexpressors by deep sequencing. This will extend the knowledge on small RNAs associated with floral transition and provide insights into the regulatory network downstream of this RNA-binding protein. Further, we will address the question how AtGRP7 orthologues function in crop species lacking FLC homologues. A barley line with highly elevated levels of the AtGRP7 orthologue HvGR-RBP1 shows accelerated FTi and preanthesis development when compared to a near-isogenic parent with very low expression of this gene. We will characterize in detail flowering of this line with respect to different photoperiods and its vernalization requirement. We will employ a TILLING approach to further delineate the function of HvGR-RBP1 in flowering. A candidate gene approach to identify downstream targets will provide insights into the signaling pathways through which HvGR-RBP1 influences FTi. This project contributes to the development of a functional cross-species network of FTi regulators, the major strategic aim of the SPP.
The classical point wise Cornell-McGuire probabilistic seismic hazard assessment (PSHA), which is widely used for seismic hazard mapping and development of design codes, does not allow direct estimation of multiple-location hazard for distributed structures and facilities: what is the (annual) probability that specific level of ground motion will be exceeded simultaneously in several sites? It is possible to extent the classical methodology to the multiple sites problem considering also ground-motion correlation. We study multiple-location PSHA, as compared with the classical point wise PSHA, using Monte Carlo simulation. Specific items are:(1) Development of the algorithms for multiple-location PSHA;(2) Analysis of the role of the geometry of multiple sites, correlation of ground motion, and evel of seimicity for multiple-location PSHA;(3) Study of correspondence and differences between multiple-location PSHA and classical point wise PSHA and analysis of possibility of utilization of classical PSHA procedures for simplified multiple-location hazard assessment.The project is innovative because only few attempts have been made so far regarding our research questions.
